ABSTRACT

Objective To investigate the effect of angelica polysaccharide (APS) on bioactivity of bone marrow macrophage (BMM?) and its relationship to hematopoietic regulation, for clarifying the hematonic mechanism of Angelica sinensis. Methods The techniques of hematopoietic progenitor cell culture and BMM? culture in vitro, biological assay of hematopoietic growth factor (HGF) in culture media of BMM?, immunocytochemistry, and nucleic acid in situ hybridization were used. Results The culture supernatant of BMM? induced by APS can enhance the CFU-Mix, CFU-E, CFU-GM; the expression of erythropoietin (EPO), GM-CSF, IL-3, IL-6 protein in BMM? induced by APS was much stronger than that in the control group at different levels; the expression of EPO mRNA and GM-CSF mRNA in BMM? induced by APS were intensified. Conclusion APS may directly and/or indirectly stimulate the BMM? in hematopoietic inductive microenvironment to accelerate the synthesis and secretion of hematopoietic regulation factors on the basis of gene and protein level, such as EPO, GM-CSF, IL-3, IL-6, which in turn to promote the proliferation and differentiation of CFU-Mix, CFU-E, and CFU-GM.
